Johnson Pump 09-1028BT-1 F7B Impeller (MC97)

The Johnson Pump 09-1028BT-1 F7B Impeller (MC97) is a genuine replacement cooling system component engineered to maintain optimal water circulation in marine and automotive engine cooling circuits. This OEM-specification impeller restores full circulation capacity after normal wear, ensuring your cooling system operates at design efficiency and prevents thermal stress on critical engine components.

Constructed from neoprene material selected for cooling system compatibility, this impeller measures 65mm in diameter with a 50.2mm width—dimensions that match Johnson Pump's OEM specifications exactly. The F7B designation confirms compatibility with specific pump housings, while the MC97 reference ties this unit to its intended marine and closed-loop cooling applications. Annual replacement is the industry standard for impellers operating in saltwater or high-temperature environments, where material fatigue from centrifugal stress and thermal cycling accelerates wear. Using a genuine Johnson Pump original ensures the impeller blade geometry, material hardness, and tolerances match your pump's internal design, preventing cavitation damage and seal degradation that can result from undersized or mismatched aftermarket alternatives.

This impeller is designed for cooling system maintenance on engines equipped with Johnson Pump circulation systems. It serves as a direct replacement for Jabsco 17937-0 units, expanding compatibility across marine propulsion and industrial cooling applications. Technicians and boat owners relying on consistent cooling performance recognize that proactive impeller replacement before failure prevents catastrophic overheating and extends engine service life. Carrying genuine replacement components ensures your next cooling system service uses verified OEM-quality parts.

The Johnson Pump brand maintains strict manufacturing standards across their pump and impeller lineup, positioning this component within professional-grade marine and industrial equipment. Proper impeller maintenance directly impacts engine reliability, making this genuine replacement a practical investment in system longevity.
